would a 215 65/15 work for a V6??..i'm currently using a 215 60/15...and bought these kumho ecsta 716's. i mean what are the cons of a bigger section ratio???
Taller, softer sidewall, which means more sidewall flex while hard or fast cornering. Not very good for quick turn-in or handling. But it depends on the tread design of the tire alot. There are some 55-series tires that handle worse than a 60-series tire. Also, keep in mind that the 215/65 is almost a full inch taller than the 215/60. You were closer to the stock diameter with the 215/60s.
